The best way to keep strong after working out for few hours at the gym is by adding to your favorite smoothie the right supplement. I recently discovered Sports Research Bone Broth Protein with Collagen and I was amazed that it contains over 20 grams of Pure Bone Broth Protein with Collagen and natural amino acids and it is dairy and gluten free. There are 3 natural flavors available Vanilla, Chocolate, and Natural Broth.
